Add an easy way to customise (move, hide, disable/add elements) the toolbox in a visualization scene.

I'd like to have an easy (or at least properly documented) way to customise the toolbox of any mayavi scene window embedded in a PyQT4 application. From searching the documentation and the web I was not able to find a working solution for this.

It would be great if one could just write some code like:
scene.toolbox.addButton(ButtonObject)
scene.toolbox.hide()
scene.toolbox.move("left") # "top", "bottom", "right"
